In this study, we investigated the Indoor and Outdoor concentrations of PM10 in Y area, Jeollanam-do. We conducted personal exposure concentration estimates, and Expoure and Risk Assessments using the Time-weighted Average Model. The concentration of Indoor PM10 was 49.38 µg/m3 and that of Outdoor PM10 was 48.02 µg/m3 , with the Indoor/ Outdoor Ratio value being 1 or more, and it was found that there was an indoor source of pollution. The Indoor/Outdoor Cr ratio value was 1 or more, and the source of Cr was confirmed to be indoor. Based on our analysis, there was a positive correlation between heavy metals Ni, Cr, and Mn (p<0.05). Using the Time-Weighted Average model, we determined the PM10 personal exposure concentration to be 49.36 µg/m3 and confirmed the feasibility of this model in utilizing the PM10 personal exposure concentrations. In this study, the find ings are likely to provide useful data that can be used to determine the concentration of indoor pollutants that are not easy to survey. However, to accurately evaluate indoor air quality, more factors need to be considered and evaluated. .

As information retrieval through internet has been popularized, a demand of medical information has been increased. But most medical information is provided by commercial web sites without evaluation the quality of information. So we suggested there were a demand for drug information supplement by special medical institutions. The aim of this research was to investigate medical information on the web sites of hospital, especially department of pharmacy, ad discuss methods of improvement. We selected the web sites of tertiary medical institutions had over 500 beds and evaluated question and answer (Q&A) sites on the webs in terms of consulting fields, overall organization and easiness of access. Among the consulting fields, we selected medicine Q&A field and estimated answering method, quality of Q&A and the time required to answer. We also conducted a verbal questionnaire survey of patients or their family to check the demands of medical information. Among the 39 institutions, 23 institutions(59%) performed Q&A on the webs and the consulting fields were mainly composed of disease(95.7%, 22 of 23) and medicine(26.1%, 6 of 23). Overall organization of Q&A sites was managed by central or each clinical department. Both management methods had similar rates(54.5%, 41%) but all Q&A sites of medicine was conducted by department of pharmacy. The access to the Q&A sites was easy regardless of consulting fields. We couldn't evaluate Q&A sites of medicine precisely because the only three web sites had conducted Q&A during the research period. As a result of questionnaire survey, 83.3% of answerers who were using internet expressed positive opinions about health information obtaining through the Q&A site of medical institution. But most people didn't know how to use the Q&A sites of hospital. In conclusion, disease consultation on the web was relatively activated but medicine consultation was very insufficient. So we should make an effort to provide medicine information on the web and discuss pharmacist's role in this part.
남해ㆍ하동 거주지역 주민의 건강영향 연구 - 건강보험자료 중심

This study examined the relevance of impact factors using survey data, standardized mortality rates, and medical utilization rates of study subjects in the Namhae and Hadong regions. The study subjects were found to have lived in the area for more than 20 years, and in terms of lifestyle, they did not smoke, but the rate of drinking was high and showed little exercise. As a result of analysis through logistic regression analysis, it was found that angina pectoris, myocardial infarction and anemia were affected by exercise status, and allergic rhinitis disease showed significant results depending on the presence of smoking. The standardized mortality rate of men in chronic lower respiratory tract diseases in the Namhae and Hadong regions was higher than in the nation. In the case of allergic rhinitis, both men and women in Namhae were slightly lower than those in Nation, and in Hadong, both men and women were higher than in Nation.
국내 일부지역의 실내공기 중 미세먼지와 초미세먼지(PM10 and PM1.0) 및 중금속 농도 분포

The goal of this study was to measure the indoor and outdoor fine and ultrafine particulate matter concentrations (PM10, PM1.0) of some houses in Yeosu and in S university in Asan from March to September 2018. PM10 concentration in indoor air in Yeosu area was 18.25 μg/m3, while for outdoor air it was 14.53 μg/m3. PM1.0 concentration in indoor air in the Asan area was 1.70 μg/m3, while for outdoor air it was 1.76 μg/m3, showing a similar trend. Heavy metal concentrations in the Yeosu region were the highest, at Mn 2.81 μg/m3, Cr 1.30 μg/m3, and Ni 1.11 μg/m3 indoors. Outside, similar concentrations were found, at Cr 3.44 μg/m3, Mn, 2.60 μg/m3, and Ni 1.71 μg/m3. Our analysis of indoor and outdoor PM concentrations in the Asan region, which was carried out using the MOUDI (Micro-orifice Uniform Deposit Impactor) technique, found that PM concentration is related to each particle size concentration, as the concentration of 18 μm and 18-10 μm inside tends to increase by 3.2-1.8 μm and 0.56-0.32 μm.
산단지역 거주자의 요중 총 비소농도와 건강영향과의 관련성에 관한 연구

In this study, 102 residents in Gwangyang and Yeosu were evaluated for exposure to levels of urethral arsenicfrom April 2017 to June 2018. The geometric mean concentration of the urinary arsenic in the total studied was154.30 μg/L, with the figure for the Gwangyang area being 201.18 μg/L and the figure for the Yeosu area being200.21 μg/L, which signifies that there was no real difference between the two regions. The figures for males andfemales were 173.81 μg/L and 136.98 μg/L, respectively, indicating higher levels for males. In the case of males,the risk assessment of arsenic (As) showed that 0.54 does not exceed 1 and approximately 11.3% exceeded thereference value. For women, the number of hazardous materials did not exceed 1.41 and approximately 5.1%exceeded the reference value of the total arsenic exposure survey.
